With only one previous owner, this 2025 Audi A1 TFSI S line is a great choice. As an Audi manufacturer-approved vehicle, this A1 S line comes with a 1.0L petrol engine and meets Euro 6 emission standards. The Audi A1 offers a large boot space, making it a practical option. The acceleration, reaching 0-62mph in 9.8 seconds, means it's nippier than other similar vehicles.
